In the given figure,the ratio of current in the $8\,\Omega$ resistor to the current in the $3\,\Omega$ resistor will be:

In the circuit shown below,the resistance of the galvanometer is $20 \, \Omega$. In which of the following alternatives are the currents arranged strictly in decreasing order?

$A$ Wheatstone's bridge is balanced with a resistance of $625\, \Omega$ in the third arm,where $P, Q$ and $S$ are in the $1^{st}, 2^{nd}$ and $4^{th}$ arm respectively. If $P$ and $Q$ are interchanged,the resistance in the third arm has to be increased by $51\,\Omega$ to secure balance. The unknown resistance in the fourth arm is ............. $\Omega$.

Kirchhoff's second law is based on the law of conservation of:

The current drawn from the battery in the given network is (Internal resistance of the battery is negligible). (in $A$)

The value of current $I$ in the electrical circuit as given below,when potential at $A$ is equal to the potential at $B$,will be . . . . . . $A$.
